Urogenital tuberculosis - epidemiology, pathogenesis and clinical features

Tuberculosis (TB) is the most common cause of death from infectious disease worldwide. A substantial proportion of patients presenting with extrapulmonary TB have urogenital TB (UG-TB), which can easily be overlooked owing to non-specific symptoms, chronic and cryptic protean clinical manifestations, and lack of clinician awareness of the possibility of TB. Delay in diagnosis results in disease progression, irreversible tissue and organ damage and chronic renal failure. UG-TB can manifest with acute or chronic inflammation of the urinary or genital tract, abdominal pain, abdominal mass, obstructive uropathy, infertility, menstrual irregularities and abnormal renal function tests. Advanced UG-TB can cause renal scarring, distortion of renal calyces and pelvic, ureteric strictures, stenosis, urinary outflow tract obstruction, hydroureter, hydronephrosis, renal failure and reduced bladder capacity. The specific diagnosis of UG-TB is achieved by culturing Mycobacterium tuberculosis from an appropriate clinical sample or by DNA identification. Imaging can aid in localizing site, extent and effect of the disease, obtaining tissue samples for diagnosis, planning medical or surgical management, and monitoring response to treatment. Drug-sensitive TB requires 6-9 months of WHO-recommended standard treatment regimens. Drug-resistant TB requires 12-24 months of therapy with toxic drugs with close monitoring. Surgical intervention as an adjunct to medical drug treatment is required in certain circumstances. Current challenges in UG-TB management include making an early diagnosis, raising clinical awareness, developing rapid and sensitive TB diagnostics tests, and improving treatment outcomes.

Congenital Tuberculosis in a Neonate: A Case Report and Literature Review

Congenital tuberculosis (TB) is difficult to detect because the disease presents few or no symptoms in the fetus during pregnancy and nonspecific symptoms in neonates. We reviewed 20 cases of congenital TB reported between 2011 and 2017 and report a case of a mother and her 8 days old neonate with congenital TB. In these 21 cases (including our case), the most common clinical presentations were respiratory distress, fever, and hepatosplenomegaly. The most common chest imaging findings were pneumonia, multiple pulmonary nodules, and miliary pattern. The mortality rate of infants with TB was increased ~2.2-fold if their mothers had no symptoms. The case reported herein concerns an 8 days old neonate with the rare presentation of a 2 days history of fever, followed by abdominal distension without respiratory symptoms. Computed tomography (CT) imaging exhibited a large amount of right pleural effusion. Multiple antimicrobial therapies were administered to the neonate; however, his symptoms persisted. Repeat CT was used to identify a progressed disease with multiple nodules over the lung, spleen, and hepatic hilar region. Standard anti-TB medications were prescribed, and the patient recovered gradually. Both gastric lavage and pleural effusion cultures confirmed the diagnosis of TB. The neonate's mother denied any TB contact history and the diagnosis of any medical disease during pregnancy, but she experienced a fulminant course of miliary TB and was admitted to the intensive care unit 24 days postpartum. She died despite receiving anti-TB treatment. In TB-endemic areas, congenital TB should be taken into consideration when neonates develop fever, respond poorly to antimicrobial treatment, and when their mothers deny any TB contact history.
